If the good leaders aren't exploitable, and they maintain unique channels of gaining momentum and attention - say via word of mouth or succeeding at gaining attention in the news or good at piggybacking on existing amplification systems (e.g. Andrew Yang running as a Democratic, otherwise would have run as Independent, due to understanding the duopoly and mainstream media's amplification of only those two main narratives), eventually the best leaders will outshine whatever bullshit takeover and noise pollution that may try to overtake the system; that still doesn't mean there won't be attempts for manipulation and narrative capture, suppression tactics used, etc.
